javascript building objects. What are the differences and best way to do it?

Question

Im trying to understand the good way of building objects. I expose two ways. Which is the best way to define an object. If both of them are fine what are the pros and cons of each one?

    var your_drink="tekila";// yes, i love tekila :)
//your_drink="";
var reverse=function(s)
{
    return s.split("").reverse().join("");
};
/*
Building objects in js.
*/ 
//first
var bartender = {
    str1: "ers",
    str2: reverse("rap"),
    str3: "amet",
    request: function(preference)
    {
        return preference+".secret word:"+this.str2+this.str3+this.str1;
    }
};
//alert result: tekila.secret word:parameters
alert(bartender.request(your_drink));
//second
var bartender = function()
{
    var str1="ers";
    var str2=reverse("rap");
    var str3="amet";
    this.request = function(preference)
    {
        return preference+".secret word:"+str2+str3+str1;
    }
};
var oBartender = new bartender();
//alert result: tekila.secret word:parameters
alert(oBartender.request(your_drink));

The second way gives you encapsulation for private attributes. You would access the private attributes using getters and setters, the way that most of POO languages do. — ioedu, Nov 18 '15 at 09:58

Food for thought

But the second way is the way to go. And read to learn about prototyping to be able to instaciate your class

To be honest I have been doing JS for some time, did not take time to read about Classes and inheritance. Now that I have, I can tell you that time will not be wasted

Tons of resources out there, some are way more accessible than others
